BAFFLE-PLATE FOR COLUMN-STILLS.

To all whom it may concern:

Be it known that I, EMILE GUILLAUME, citizen of France, residing atParis, in the said Republic, have invented new and useful Improvementsin and Relating to Baffie-Plates for Column-Stills, (for which I haveobtained a patent in France, No. 5162/ 320,850, hearing date May 26,1905, and in Republic, No. 4493, of February 7, 1906,) of which thefollowing is a specification.

This invention has for its object certain improvements in thearrangement of battle plates for column stills described in my U. S.Patent No. 732,548.

In order to properly understand the improvements in question it isnecessary to refer to the specification and drawings of the said patent.It will there be seen that the characteristic feature of the inventionis to constitute along the whole lengtl of the lower edge of thepartition 3 of each plate, a continuous sheet of liquid, which, when thevapor rises in the direction indicated by the arrow in the drawings ofthe said patent, is atomized and projected in a continuous spray whichextends longitudinally along the wall 3 and into the space comprisedbetween the latter and the wall of the still facing it. Under theseconditions if the ascent of the vapor is stopped, a vertical curtain ofliquid along the whole length of the wall 3 .is obtained, which fallsonto the lower plate; if the ascent of the vapor recommences, itencounters said curtain so as to produce the continuous sprayhereinbefore mentioned and does not permit the vapor to rise from oneplate to the next without having passed through the freely falling sheetof liquid.

It may also be pointed out that with this arrangement the followingdrawbacks may be encountered :,If the discharge of the liquid is suchthat the orifice 2 is insuflicient,

the plate then becomes filled up to the level of the upper part of thepartition 3 and then the liquid overflows this latter; there resultsfrom this a diminution of the free space for the passage of the vapor,which is caused to pass through the liquid in the form of bubblesproducing an agitation prejudicial to the good working of the aparatus.If, on the contrary, the discharge of the liquid becomes insuflicient toproduce a full flow of the liquid through the orifice 2, there willresult differences of thickness Specification of Letters Patent.

in the sheet, and-even openings'through which naturally the vapor willtend to pass by preference, without acting in the characteristic mannerof the present system. Finally, if theorifice 2 becomes stopped inplaces in consequence of impurities carried along by the liquid, thesame inconvenience as the foregoing will be produced.

The improvements forming the object of the present invention, have fortheir object to remedy the drawbacks hereinbefore stated.

The invention is illustrated in the accompanying drawings in which,Figure 1 is a vertical sectional view of the invention applied to arectangular still. Fig. 2 is a like view of a slightly diii'erent form.Fig. 3 is a sect-ion through a cylindrical column, having plates notprovided with longitudinal orifices. Fig. 4: is a view similar to Fig. 3but showing a column having plates, provided with longitudinal orifices.Figs. 5, 6, 7 and 8 are detail views.

According to my invention, apertures 5 are arranged along the partition3, which apertures prevent the plate filling with liquid up to the topof the partition 3, thus avoiding the first of the drawbacks herein myU. S. Patent No. 732,548 may then be completely suppressed, and all theliquid will flow through the apertures, which will avoid the twootherdrawbacks hereinbefore specified. On the other hand in order toavoid, in case the orifices 2 are retained, the third of the drawbacksin question, that is to say the obstruction of the said orifices, theslope of the plates is directed downward toward the outside of thestills, thus producing a reserve of liquid retaining the refuse whichmight cause this obstruction.

In the Fig. l are shown the plates of a rectangular column still inwhich the orifice 2 is retained, butin which it is supplemented byapertures 5 uniformly distributed over the whole length of the verticalpartition 3.

These apertures 5 serve as intermediate advantage, over that shown inFig. 1, of

considerably sim lifyin the construction of the plates, an of defectiveworking, which would arise wit the plates shown in Fig. 1, in'case thequantity of liquid which has to pass through the orifice 2, should notbe sufiicient to cause the full sectional flow. to take place. The twoupper plates of Figs. 1 and 2 are shown sloping toward the verticalpartition 3, that is to say in the direction of flow, and the two lowerplates with an inclination in the opposite direction. There is anadvantage I in em loying the former when it is desired to re uce to astrict minimum the volume of liquid on the plates, while the second areemployed when it is desired to increase this volume a little andespecially when it is desired to regularly withdraw, to the outside ofthe still, liquid from these plates. Further, b the use of the latter,the discharge ori ces 2 and 5 run less risk of becoming stopped becauseany refuse capable of doing this will, with that construction, preferablgravitate toward the external part of t e plates, that is to say toward6. In both cases, however, the volume of liquid in action over the wholeof the plates of a column of given production, always remains much less,relative to its hourl production, then when scrubbing pl'ates of anordinary type, either perforated or dished ones are employed.

In Figs. 3 and 4, the left hand part represents the external plates 7,with a slope leading toward the exterior wall of a cylindrical column,and the right hand part represents the plates with a slope in theopposite direction; some of the internal plates 8 are shown slightlyconvex and the others slightly concave. What has beenheretofore statedrelative to the selection of the direction of inclination for the1plates shown in.

Fi s. land 2, applies e ua sh wn in Figs. 3 and 4;.

In Fig. 5 small grooves 9 are shown, starting from the base of theapertures 5, which grooves were made in the first experiments in .orderto facilitate the uniform distribuy to the plates tion of the liquidover the whole length or,

greater security avoi ing the possibility periphery of the lower edgeofthe partition 3; t ese grooves which may be simply roduced by means of agravers chisel a 0rd of the desired result being obtained but they arenot indispensable.

Figs. 6, 7 and 8, represent a form of the openings provided with ashield 10, formed by cutting the metal of the portion 3 on three sides,and bending the tongue thus formed out the lane of said portion, inorder to prevent t e passage of, a portion of the' steam orvapor throughthe apertures 5 iii it is feared that such a-passage might take p ace. I

The shields 10, above specified may be turned either toward the exteriorof the plate, as shown in Fig. 7, or toward the interior, as shown inFig. 8. v

Naturally, it is not necessary, that the apertures 5 should include, atthe same time, the grooves 9 and shields 10 specified above. Theapertures can include either the grooves 9 alone, as indicated in Fig.5, or the shields 10 alone, as indicated in Fig. 6.

The columns shown in Figs. 3 and 4 are provided with plates havingapertures rovided with grooves but without the shield. The scale ofthedrawing does not permit of representing these grooves clearly on-Figs. 3 and 4, but they are of the same kind as those shown on a largerscale in Fig. 5 0f the drawing.

Having now particularly described and ascertained the nature of my saidinvention, and in what manner the same is to be performed, I declarethat what I claim is 1. In a system of baflie plates for rectangular orcylindrical columns stills, a partition (3) having apertures (5) formingoverflows, along the whole length of the periphery thereoi, the saidapertures being uniformly distributed and placed at the same level, andhaving small grooves (9) starting from their base in order to facilitatethe uniform distribution of the liquid. 4

2. In a system of baflle plates for rectangular or cylindrical columnsstills, a partition (3) having apertures (5) forming over-- flows, alonthe whole length of the periphery thereo ,the side apertures beinguniformly distributed and placed at the same level and being providedwith a shield (10) to prevent the passage of the vapors through the saidapertures.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

I I EMILE GUILLAUME.
